The Vestibular system is the part of your inner ear which helps you maintain your balance. This system works in conjunction with your eyes and movement sensors on the skin, muscles and joints to help to maintain balance and equilibrium. If there is a disturbance in one of these systems or in the pathways that allow them to communicate with the brain or with each other, the patient will feel dizzy or unsteady.
Cairns Audiology Group works closely with local and national Ear, Nose and Throat Specialists, Neurologists, Allied Health Providers and General Practitioners to aid in the assessment of the vestibular system and identification of peripheral and central vestibular pathologies.
Our university qualified Audiologists are trained in the latest assessment techniques and use state of the art technology to ensure accuracy of results.
Assessment of the vestibular system is conducted through a series of tests designed to measure the vestibulo-ocular reflex via eye movement. Videonystagmography, the measurement of this reflex, is achieved through the patient wearing infra-red video goggles which allow close monitoring and recording of abnormal eye movements.
Optokinetic Tests require the patient to follow a series of light patters on a TV screen to measure the reflex.
Positional Tests measure the response of the vestibular system to changes in head and body position.
Bithermal Caloric assessment involves warm and cold air being blown gently into the ear for about one minute. The temperature change created causes the fluid in the semicircular canals to move and the degree of response is compared between ears to monitor for any weakness on an individual side.
